User manual - METER SRT-N118-XA
- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,
humidity, corrosive gasses and oils.
- Do not use the unit in areas where there is risk of explosions.
- Do not use the unit in areas with significant temperature variations, exposure to
condensation or ice.
- Do not use the unit in areas exposed to direct sunlight.
- Make sure that the ambient temperature (e.g. inside the control box) does not
exceed the recommended values. In such cases forced cooling of the unit must
be considered (e.g. by using a ventilator).
The unit is designed for operation in an industrial environment and must
not be used in a household environment or similar.

GENERAL CHARACTERISTICS
meter is equipped with thermocouple input (K, S, J, T, N, R, B, E).
The measurement range depends on connected thermocouple type. Measurement is
linearised by the polynomial characteristics referred to particular thermocouples and
temperature of cold ends is compensated automatically. The device has additional
measurement range (-10
÷
90mV) mainly for diagnostics of measurement circuits. Being in this
range, unit displays direct voltage connected to its input (without compensation of cold ends).
The result is presented on 4-digit LED display. For every thermocouples result is displayed as
integer (no decimal point, e. g 1460) and for mV range with 2 digits after decimal points (with
resolution 0.01mV e. g. -1.23 ).
can be equipped with: two relay outputs, two OC type outputs, one relay
and one passive isolated current output or one OC type and one passive isolated current
output. Device
is equipped with RS-485 / Modbus RTU communication
interface and 24V/100mA supply output for free use. The meter can be ordered in two power
supply versions.
The device has 4 buttons being used for main presets programming. To get high
protection level, the keyboard is mounted under transparent cover. To allow user to change
presets without opening the cover, an IR sensor is mounted. Remote controller keyboard is
equivalent to the device keyboard (Note, that remote controller is not a part of the
set – it is an additional equipment).
